HARTWELL L. WILLIAMS, OF RISON, ARKANSAS.

SINGLE-TRIGGER MECHANISM'FOR DOUBLE-BARRELED GUNS.

Application filed February 25, 1913.

To all 'whom it may concern:

Be it known that I, HARTwnLL L. WIL- LIAMS, citizen of the United States, residing at Rison, in the county of Cleveland and State of Arkansas, have invented certain new and useful Improvements in Single- Trigger Mechanism for Double-Barreled Guns, of which the following is a specification.

This invention relates to firearms and more particularly to single trigger mechanism for double barreled guns.

The main object of my invention is the provision of mechanism whereby bot-h barrels of a gun may be discharged successively and either alternately from right to left or from left to right, the mechanism being underA the control of the operator so that he may fire either barrel rst as he may desire.

A further Objectis to improve the detail construction of the means for setting the mechanism to fire either barrel, and in this connection to provide a setting member movable from a safety position to a position to lire either one or the other of the barrels as it is desired and to provide indicating means whereby the position of the setting mechanism may be observed.

A still further object is to provide simple and novel mechanism for positively preventing the simultaneous discharge of both barrels when one is discharged, caused by the involuntary pull due to the recoil of the gun, and in this connection specifically to provide a catch or stop adapted to be engaged by the hand of the operator and movable upon the recoil of the gun into position to prevent the actuation of the trigger and immediately and automatically movable out of such position upon a rebound of the gun from its recoil.

A still further object is to provide single Vtrigger mechanism for double barreled guns of such simple character that it may be easily assembled or disassembled and which shall be simple and durable in construction, positive in action and applicable to any of the styles of double barreled gun common in use.

A further object is to provide safety mechanism for locking the trigger and selector mechanism in their downward or inoperative position.

Y A still further object is to provide for the passage of the tang screw through the lower tang or lock plate, thus eliminating bridg- Speciiicaton of Letters Patent.

ing usually resorted to in mechanism of this nature in order to make connection between the upper and lower tang plates, and further to so form the parts that the tightening or loosening of the tang screw shall have no eect upon the operation of the safety locking mechanism, thereby eliminating the necessity of continually adjusting the tang screw.

A further object is to provide housing for the actuating mechanism, so constructed as to thereby prevent the mechanism from becoming wood bound by the stock or otherwise obstructed.

Other objects and advantages will appear in the following description.

My invention is illustrated in the accompanying drawings wherein:

Figure 1 is a side elevation of a portion of a double barreled gun, the frame thereof being broken away to show the trigger actuating mechanism. Fig. 2 is a top view of the construction shown in Fig. l but sectioned on the line 2-2 of Fig. 1. Fig. 8 is a like view to Fig. l but showing the trigger mechanism in the position assumed when the selector has been set for firing the right hand barrel first and after the trigger has been pulled and the barrel fired, the ligure showing the right hand sear as raised and the trigger locked in its raised position by the recoil operated trigger lock. Fig. l is a like view to Fig. 3 except that the trigger is shown as released from the raised posi.- tion, as in Fig. 3 allowing the automatic slide to move forward into a position where its transverse lugs rest under both sears so that at the next actuation of the trigger, both sears will be raised to discharge the unfired or left hand barrel. Fig. 5 is a perspective view of the sears, the trigger, the selective actuating member and the automatic sear actuating member detached from each other. Fig. 6 is a perspective view of the slide, the dogs, the locking lever therefor, the safety lever and the link, the parts being separated from each other. Fig. Ga is a perspective view of the slide, locking lever and allied parts assembled. Fig. 7 is a perspective view of the selector locking member which forms a-housing for the selector and the automatic sear actuating member and the lever for actuating the automatic sear actuating member. Fig. 8 is a perspective view of the recoil operated trigger lock detached from the stock. Fig. 9 is a top view of the upper tang and the slide 81 and showing the graduations on the tang coacting with the slide. Fig. 10 is a fragmentary top plan'view of the sears and the lower end of the selector in section and showing the selector in position to cause the firing of the right hand barrel, this view also showing in dotted lines the selector in position to cause the firing of the left hand barrel. Fig. 11is a face view of the lower tang 2 showing the trigger slot in the lower tang, the trigger and the transverse groove lll in the face of the lower tang.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

My improved single trigger mechanism as before stated is applicable to any of the well known types of double barreled Vguns now in use and such a gun is illustrated in the figures. In these figures, A designates the barrels of the gun, B the frame, C the stock and D the top snap lever. The stock is connected to the frame B bythe usual upper and lower tangs or lock plates, designated respectively 1 and 2. The lower'lock plate-2 -v is formed with a longitudinal slot 3, through which operates the trigger 4;. The trigger 4 consists of a vertically disposed, longitudinally extending blade having the usual curved linger piece attached thereto. The trigger is pivoted at its forj ward end as at 5 in the slot 3 of the lower tang. "The free end or back end of the trigger is formed with a notch 6the purpose of which will be later described.

Mounted upon the tangV 2 by means of screws or in any other suitable manner is a trigger safetyY lock vdesignated 7 andillus# trated in Fig. 7. This trigger safety lock isV rectangular in form,`that is, it forms va casing open at its upper end. lThe casingv comprises a bottom 8 and two upwardly extending sides 9, the upper edges of the sidesat their rear end being downwardly beveled as at 10. The forward ends of the sides 9 are formed with projecting ears 11 which are preferably rounded. This trigger safety lock member is attached by screws passing through the bottom 8 into the tang 2 and is of course fixed'in position. y

Disposed within the housing formed by the member 7 and specifically between the two sides 9 of said member is a sear actuating slide 12 illustrated in Fig. 5. This slide is L-shaped in form, that is, has a down-A wardly v extending forward end 13 and is substantially U-shaped in cross section, the lateral walls of the slide being longitudinally slotted as at 14:, and the bottom of the slide also longitudinally slotted. The downwardlyV extending nose 13 is preferably solid and at its lower end has the laterally projecting lugs 15 forming a cross'bar at the lower end of the nose. i The rear end of the sear actuating slide is closed by a wall 16.

Mounted within the sear actuating slide y 12 and longitudinally movable with relation thereto is the selector slide 17. This slide is formed with a longitudinally extending vertical slot 18 for the passage of the tang screw as will be later described and is also formed'at its forward end with the downwardly and forwardly projecting nose 19, this nose -being preferably solid. The under face of the vlower end of the nose is longitudinally grooved as at 20 for the reception of the upper edge of the trigger 4 as-illus-fY The rear end of the slide 17 is suplongitudinally spacedfrom each other so i that thelug Y21 is disposed in advance of the lug 22. In other words, thesek lugs 21 and 22 are disposed out ofvalinement withv 'y each other. f

Pivotally vmounted within the Vframe B are the sears 23 and 24.' T-hesev sears eX- tend longitudinally of the gun and are disposed slightly above the forward end of the tang 2. TheY forward ends of the sears are beveled and engage with any suitable 'hammer mechanism.

A s illustrated in the drawings, each barrel 1s provided withl a hammer F adapted to engage a cartridge or firing pin. The j j lower end of the hammer isnotched forengagement by the beveled end of the sear. 'A

When ther sear is raised it is released from the hammer and a hammer spring'thrcws the hammer. forward into engagement with the firing pin. The hammer construction is so well known that it needs no special description, and furthermore my mechanism maybe varied to suit any .particular-hammer construction desired.

rlhe sears, of course, extend rearward one on each side of the downwardly-extending nose 19 of the selector 17 and each sear is formed upon its inner face with an inwardly projecting lug 25 adapted to be engaged by the lugs 21 or 22 of the'selector. The nose 19 of the selector is also provided above the lugs 21 and 22 with Vlaterally projecting safety pins 26 adapted to engage beneath the ears 11 onthe trigger safety locking member 7 when the parts are in the safety position illustrated in Fig. 1.V Y

Y The rear end of the slide 17 of the selector is reduced in thickness and disposed `be`- tween spaced plates 27 whose upper ends are beveled to form teeth 28. These plates27'- together form oppositely disposed spaced iic stop dogs or detents, the purpose of which will be later described. The plates are held in engagement with each other and with the slide 17 by means of a screw 27 a and by an oppositely projecting lug 27b which holds the plates in alinement with the plate 30 of the slide. 31.

Passing through the stop dogs or plates 27 is a pin 29, this pin passing through the reduced rear end of the slide 17 as illustrated in Fig. 5, passing through the lower ends of the stop dogs 27 and through the slots 14 of the member 12. Disposed between the plates 27 and held thereto by the screw 27a and the lug 27b or in any other suitable manner is an upwardly extending arm 30 which extends through a slot in the upper tang 1 and is connected to a safety slide 31 which moves upon the face of the tang l, this slide having a rounded protuberant middle portion laterally scored in order to provide for firm engagement with the thumb of the operator. The forward end of this slide is formed with a sight opening 32.

Depending from the upper tang plate 1 is an ear 33 and pivotally connected to this ear is a longitudinally slotted friction stop lever 34. This is longitudinally slotted in its bottom for the passage of the arm 30. Preferably this stop lever is formed as illustrated in F ig. 6 of one piece of metal bent upon itself to form upwardly extending sides which embrace the arm 30. These sides are formed with a plurality of notches 35, there being three of these notches and these notches coacting with the pointed stop dogs 27. The forward end of the friction stop lever is open for the passage of a pin 36 which depends from the under side of the upper tang 1 and is enlarged at its lower end so as to limit the downward movement of the friction stop lever. A coil spring 37 is disposed around this pin and between the under face of the tang 1 and the upper face of the lever. The side walls of the lever 34 are cut away at the forward end so as to provide a reduced or flattened portion against which the spring 37 bears. It will be seen that the action of this spring 37 is to force the lever down with its notches in yielding engagement with the beveled or pointed upper ends of the step dogs 27. Corresponding to the three notches 35 are three graduations or spaces 38, 33a and 38h, these spaces or graduations being marked upon the upper face of the tang 1. The space 38 corresponds to the first of the notches 35 and to the safety position of the slide and therefore within this space is marked the letter S which when the slide 31 is in safety position is displayed through the opening 32. In the next following subdivision there is the letter R indicating that when the slide is moved to a position' where vthe letter may be seen through the opening 32, the right barrel will re upon a pull of the trigger, while in the next succeeding space 38h, there is marked the letter L which when displayed through the opening 32 shows that the slide 31 has been moved to such position that the left barrel is capable of being iired. The means whereby the firing of the right and left barrel is secured will be seen from further description but it will be obvious that when the slide 31 is moved to the safety position, the pins 26 on the downwardly projecting nose 19 of the selector will project laterally beneath the ears 11 and that therefore the selector, and therefore the trigger, will be held from any upward movement and held at safety Pivotally mounted between the rear ends of the sides 9 of the housing and safety lock 7 by means of a pivot screw 39 is an actuating lever 40. rIhis is approximately angular in form and is made of a relatively wide strip of metal which is longitudinally slotted as at 40a (see Fig. 7 The free end of the actuating lever is outwardly bent or curved as at 401 and normally bears against the rear end 16 of the sear actuating slide 12. 1t is curved as at 40b for the purpose of presenting a good bearing face to the rear end 16 of the slide without regard to the angle of the lever 40. The lever 40 is urged upward and forward by means of a spring 41 mounted on an upwardly and forwardly curved post 42 projecting upward from the lower tang 2. lt will'be seen that the tendency of this spring is to force the lever 40 upward and forward and thereby force the sear actuating slide forward. Further it is to be particularly noted that the slot 14 of the slide 12 is located near the bottom of the slide whereas the free end 40b of the lever 40 engages the upper portion of the back 16. The sear actuating slide is practically fulcruined upon the pins 29 projecting from the lower ends of the stop dogs 27 and hence the tendency of the lever 40 urged by the spring 41 is not only to push the sear actuating slide forward but also to rock it upon its fulcrum so as to throw the forward end or nose 13 of the slide downward for a purpose to be later stated.

The rear ends of the upper and lower tangs 1 and 2 are connected by means of the tang screw 432L while a tang screw 43 passes through the middle of the upper tang 1, downward through the slot in slide 17 through the bottom of the slide, through the bottomof the trigger safety locking member 7 and into the lower tang 2, and it will therefore be seen that this tang screw 43 acts to guide and steady the slides 12 and 17, and further that these slides are not only guided by the tang screw 43 but by the upwardly projecting arm 30 which passes up through the slot in the upper tang.

Slightly in advance of the lower forward corner of the trigger safety locking memsear actuating ber 7, the lower tang plate 2 is transversely grooved as at 44. This groove is intersected by the longitudinal slot in the tang 2 through which the trigger 4 operates. The rear end of the trigger 4 is'cut away as at 6 so as to p rovidea shoulder 45. This cutaway portion 6 approximately coincides with` the Vgroove 44 and the lugs 15 of the nose 13 of the sear actuating slide 12 normally rest in this groove 44 as illustrated in Fig. 1. When the trigger is pulled, however, as illustrated in Fig. 3, the forward end of the sear actuating slide will be raised against the force of the spring 41 until such time as the lugs 15 lift beyond the upper face of the tang 2, whereupon the spring 41 acting through the lever fwill force the sear actuating slide forward and beneath the sears as will be later explained.

1t was stated above that the cutaway portion 6 of the trigger 4 approximately fitted and corresponded with the shape of the groove 44. IThis is true, with this exception, that the back end or shoulder of the cutaway portion 6 does not extend to or even with the adjacent wall of the groove 44,

that is, the cutaway portion 6 is longer than the width of the groove 44.

YThe lower portion ofthe nose 13 of they sear actuating slide A when resting in the groove 44 of the tang 2, also rests upon the top edge of the trigger 4 and consequently will be raised up and out of the groove 44 when the trigger is raised; Thus when the trigger is raised, as shown in Fig. 3, the

forward end of the automatic sear actuating slide is freed from the groove 44 and this allows the forward end ofthe slide to move forward in the cutaway portions 6 until the lower end of the nose 13 strikes the shoulder This shoulder as previously stated is disposed forward `of the groove 44 and therefore since the nose 13 is resting against the shoulder 45, the lugs 15 will have moved forward and out of line with the groove 44 extending so that when the trigger is released or allowed to descend, the lugs 15 and the nose 13 will strike the top surfaceV of the tang 2 forward of the groove 44 which stops their downward movement, causing them to slip over the shoulder 45 of the trigger as the trigger descends to its downward position. vThis now leaves the sear actuating` slide freeto move forward Vunder the influence of the lever 40 untilthe lugs 15 rest under the sears 23 and 24 as in Fig. 4 and since the nose 13 rests on top of the trigger 22, if the trigger be again. raised while the sear actuating slide is in this position, both of the sears will be raised. The operation of this part of the invention is as follows: 1n the position shown in `Fig. 1 which is the safety position, the slide v31 is vat its safety position with the letter S disof the sears.

. played through the opening 32. As a consequence the dogs 27 are engaged with the rear-morst notches 35. The slide 17 is drawn rearward so that the lugs 21 and 22 are rearward of the corresponding lugs on sears 23 and 24, the pins 29 at the rear ends of the slots 14 and as a consequence the sear actuating slide 12 is held in its rearmost position forcing back the lever 40 and compressing the spring Y41. on the nose 13 of the sear actuating slide are disposed within the groove 44, being held therein by the downward pressure upon the forward end of the sear actuating slide caused by the lrotative action of the lever 40 as previously stated. rlhe trigger is, of course, forced down and held in its downward positionl bythe downward v'force keX- erted upon the forward end of the sear actuating slide. lnasmuch as the selector 17 is drawn rearward, the safetypins 26 are eX- tended beneath the locking lugs 11 of the housing and trigger safetyloclr 7, thereby p locking the trigger. If now it is desired to permit theforward -inovernent of the searV At this period the lugs 15 actuating slide when released. rlhe forward movement of the selector carries the safety pins 26 from underneathV the lugs'11 and also carries-the lug 21 beneath the lug or shoulder 25 on the sear 23, that is, the sear for the'v right hand barrel. 'ln this position,

as is seen by reference to Fig.v 10, the lug 22 will be behind-the lug 25 of sear 24, and upon a vertical movement of the nose of the -selector the sear 24 will not be actuated. `Upon pulling the trigger, the trigger will move upward against the force of spring 41 which will shift the selector upward and the lug 21 will engage with nthe lug 2.5 on

vsear 23 and trip the sear 23, tripping the hammer in the usual manner. As soon Vas the trigger rises, it will lift the nose 13 and the lugs 15 out of the groove 44 and the slide will move forward until thelugs 15 strike against the shoulder 45 on the trigger.

When now the trigger is released and moves downward, the spring 41 acting upon the lever 40 will shift the slide still farther forward so as to carry the lugs 15beneath both actuated it will lift the nose 13 ,of the sear 'actuating slide and the lugs 15 Vwill throw up both sears, thus tripping the hammer whichA was not tripped before, `that is, the left hand hammer. Preciselyr the same op-y eration occurs if the slide 31 be'shifted forward so that the letter L is displayed 1f now .the trigger beagain through the opening 32, only in this case as will be plain from Fig. l0, the nose 19 of the selector slide 17 will be moved so far forward that while the lug 22 will come beneath the lug 25 of the sear 24, the lug 21 will be shifted to a point in advance of the lug 25 of sear 23 so that when the selector rises under the impulse of the trigger, the lug will engage with sear 24 but the lug 2l will escape the lug 25 of sear 23 and the left hand barrel will be fired. Here again upon a second actuation of the trigger the other barrel will be fired.

Tn order to provide mechanism whereby the firing mechanism may be returned to its safety position if it is in a firing position and the gun is broken or the top snap D is turned so as to permit the opening or breaking of the gun, I provide the return safety lever designated 46 which is pivotally con- -nected at its lower end to the lower tang 2 as at 47. The upper end of this lever is pivotally connected as at 48 to parallel rods or links 49 which are spaced apart sulficiently to permit the passage of the tang screw 43 and which extend rearward and at their rear ends are pivotally connected by a pin 50 to an ear 5l projecting from the arm 30. The forward edge of the lever 46 intermediate its ends is thickened or provided with a curved faced shoulder 52 which is disposed immediately opposite to the locking pin 53 of any ordinary or usual construction and which is connected to the top snap D in such manner that when the top snap is rotated to an angular position with relation to the frame and stock so as to permit the gun to be opened, the locking pin will be protruded. This breech lock mechanism is a common construction and forms no part of my invention and therefore re` quires no further description. The object of curving the face of the shoulder 52 is to present a proper bearing surface at all times to the breech lock 53. It will be seen that when the mechanism is in the position for firing either the right or left hand barrel, the return lever 46 will have moved forward and toward the breech lock 53. Hence when the breech lock is actuated by the top snapD it will move rearward and will strike the shoulder 52 of the lever 46 and will force this lever backward. As the lever 46 is connected to the lower extension or arm 30 of the safety slide 3l, the firing mechanism will also be moved backward into safety position. It will, of course, be un` derstood that the movement or stroke of the lever 46 is to be regulated so that the upper end of the lever will travel rearward a distance sufficient to carry the arm 30 and the slide 31 to safety position. This may be accomplished by lengthening or shortening this lever 46.

It has been found by tests that where a single trigger is employed to discharge both barrels of a gun, the recoil of the gun, when one barrel is tired, will cause what is termed an involuntary pull on the trigger by the operator, thereby firing the other barrel unintentionally. An explanation of this action is that the recoil of the gun carries the gun backward and against the shoulder of the gunner, causing the trigger finger to move forward, so to speak, relatively to the trigger, but in reality the trigger is moved backward with the backward movement of the gun on the recoil, therefore moving the trigger away from the trigger finger and allowing its release. At this instant the resistance of the shoulder of the operator and the elastic return of the muscles of the shoulder to their normal position, causes the gun to rebound quickly and by this rebound the finger is again thrown against the trigger causing the said involuntary pull and causing the other barrel to be fired. To positively prevent this involuntary pull, I have provided mechanism operated by and in ab` solute accordance with the recoil and rebound of the gun whereby the trigger is locked for an instant and then again released.

The trigger as shown in Fig. 5 is provided with a recess 54 at its rear end adjacent to the linger piece and beneath the recess 6. This recess is so located that it is normally below the level of the lower face of tang 2 but when the trigger is raised, the longitudinal wall of the recess is brought Hush with the face of the tang. Mounted upon the under face of the tang 2 is a slide bolt or lock 55 which is formed with a downward extension 56. The bolt or lock is rectangular in form but the extension is in the form of a relatively thin vertically disposed web though made integral with the bolt. The extension passes through and operates within a slot 57 formed in the downwardly extending portion 58EL of the trigger guard 58 and formed integral with this extension but disposed upon the outer face of the trigger guard is a transversely extending plate 59 which is curved to conform to the curved portion 58a of the trigger guard and then extends longitudinally along and bears against the under face of the tang 2 and the under face of the stock as at 60. This portion 60 which is long enough to provide a full bearing face for the fingers of the operator is roughened, knurled, serrated, or otherwise formed so that the fingers of the operator may secure a good grip thereon. This portion 60, which, as before remarked, is integrally connected with the portion 56 and the lock 55, is longitudinally shiftable in relatively small limits along the under face 'of the stock and tang provi-ded that the trigger llO ' which the finger is away from the triggerV is raised. lVhen the trigger is raised and-'the lock shifted in one direction toward the muz-V 'zle of the gun, the locking member 55 will shifted when the V trigger is raised as when'V the trigger is not raised, as in lfig. l, the

end of the trigger protrudes below the level of the under face of the tang 2 and locks the locking member securely in its rearward position. The hand of the operator, due to the recoil, forces the locking member into engagement with the notchor recess 54` only when the trigger is raised and a shot fired whichrproduces recoil. The trigger is intended thereby to be locked for an instant in its raised position during the instant in due to the backward movement of the gun on the recoil.

rEhe slidinglocking member 55 is provided with a longitudinally extending slot 61, the side walls'of which are shouldered or rabbeted as at 62, and disposed in this ,slot and having engagement vwith the longitudinal shoulder 6.2 is a bloc'lr 63 held in place by a screw 64 which passes into thetang The block may be held in place by means of the screw 64 but in guns which will permit, it is preferable to allow the tang screw 43 tov extend through the lower tang 2 and into the block 63 as illustrated in Fig. 3. The numeral 64, therefore, indicates the extremity of the tang screw.

The knurled, matted or serrated extension or sliding portion has at its rear end an upwardly extending lug 65 which ts in a longitudinal slot 65a formed in the rearward extension of the trigger guard 58, this extension being designated 66. This extension ofthe trigger guard is attached to the lower tang 2 and extends beyond the length of the tangv 2 and is held to thevstoclr by a screw 67. The upwardly extending lug 65 is perforated to receive a transverse pin 68 which when fitted in the lug 65 fastens the rear end of the matted extension 60 to the extension of the trigger guard but leaves the extension 60 together with the sliding locking member 55 free to slide back and forth. It will be understood that there are many methods which kmay be employed to support the extension 60 and bring about the same results as described.

1t is to be noted that the slot 65a is narrowed at its rear end so as to iit Vsnugly the lug 65. The lug 65 moves forwardonly a relatively short distance. It does not therefore move far enough forward to passenthe stock should be recessed to receive pin 68 and allow its movement forward 'with lug 65. The pin 68 acts as a key pinning the extension 60 to the under face of extension 66 but allowing the longitudinal movement of the extension 60 as the pin 68 is free to slide upon the face of extension 66.

want it especially understood that in-V stead of being matted or lnurled, the extension 60 may be constructed with hog backs or curved recesses, curved to fit the fingers or may be formed in any other manner to insure a reliable connection between the extension 60 and the fingers of the operators hand when the hand grasps the stock in a natural way so as to insure the backward or forward movement of the sliding locking member 55 upon the recoil and rebound of the gun.

ln order that it may not be necessary to rely upon the rebound of the gun alone to move the recoil trigger locking slide 55 back and out of notch 54 of the trigger after a shet has been fired, a spring may be provided and so placed that its force will be exerted backward and on the extension 60 so that when the trigger locking slide moves forward, due to the recoil it will move against they force of this spring and the spring will act to force the slidebackward again to its released position after the force of the recoil is spent. In Fig. 1, VI show one form of this spring. In this figure, 70 desig-` nates a coil spring which isdisposed in a recess 71 formed upon the inner face of the extension 60 'and in va slot formed in the extension 66 of the trigger guard. This spring bears at one end against the rear end of the lower tang 2 and at its other end Y bears against the upright lug 65. It will be member 55 out of engagement with the` notch 54. I do not wish to'be limited,`how ever, to the use of this mechanism for normally holding the lockingbolt or slide 55 out ofengagement with the notch 54 as a spring catch or a friction catch or any other suitable catch may be provided which will hold the recoil trigger locking slide in its position firmly enough to insure its remaining in its rearward position until it is forced forward and out of the catch by the recoil of the gun. It will be seen in Fig. 1 that the rear end of trigger 4 when the trigger is down or in its normal position holds or locks the recoil slide firmly in its rearward position. The friction catch mentioned above would hold the slide in its rearward position before the operator releases the trigger and after having fired one barrel, that is, would hold the slide in its rearward position when the trigger is raised.

The operation of the mechanism which I have described for locking the trigger upon the recoil is as follows: Tn Fig. 3 the mechanism is shown as being set to fire the right hand barrel, the left hand barrel having been fired. Assuming that the right hand barrel has not been fired although the mechanism has been so set, then immediately that the trigger is pulled, there comes a recoil of the gun. By reference to Fig. 3 it will be seen that the recoil has forced the gun back and left the trigger locked in its raised position while the trigger finger has moved forward, that is to say, the gun has moved backward leaving the trigger finger forward. New the rebound comes instantly7 throwing the gun forward again. If the trigger had been allowed to release, the trigger linger would strike it and raise it again as the gun moved forward on the rebound but the locking member has kept the trigger locked in its raised position so that when the gun again moves forward on the rebound, the finger does not find the trigger released but is forced on back and against it in its raised position and strikes it just at the moment that the locking member moves out of the recess 54, due to the gun moving forward on the rebound. As the hand of the operator grasps the matted eXh tension 60 when the gun moves forward on the rebound, the locking member lwill be moved out of the recess 54. This now leaves the finger against the unlocked trigger in its raised position and since the recoil and the rebound are both over the trigger is free to be released for the neXt shot. It is particularly to be noticed at this point that no direct trigger spring is used. The downward force of the sear springs is relied on for this purpose. Then the gun is fired or either sear is raised, it will be noted that the sear offering a resistance due to its spring exerts a downward force upon the lugs 21 or 22, as the case may be, thereby transmitting this downward force to the selector which rests on top of the trigger and forces the trigger downward. When on safety, the trigger and selector are held down by the safety lock. llien off of safety one or the other of the lugs 21 and 22 rests under one or the other of the shoulders 25 of the sears.

In some single trigger mechanisms where it is desired that only one sear be raised in firing the second shot instead of both sears being raised, as in the gun illustrated in connection with my invention, a cam surface is constructed upon the hammers below the notch where the sears engage. This cam surface when the hammer is released, comes in Contact with and bears or presses down upon the end of the corresponding sear keeping the sear in a raised position until the hammer is again cocked. Therefore the sear of the discharged barrel is left in a raised position leaving the sear of the loaded barrel to be raised alone at the next pull ofthe trigger. This construction of hammer and sear forms no part of my invention and I have not illustrated it, but it will be perfectly well understood that the principle of my invention may be applied to this form of hammer where the results as described are desired, but in all these cases a direct trigger spring is rendered necessary in lieu of the indirect trigger spring created by the action of the sear springs.

The operation of my invention is as follows: n Fig. 1 the mechanism is seen at safety, from which position if it be desired to fire the right hand barrel first, the safety slide 3l is shifted forward until the selector stop dogs rest in the middle notch of the notches 35 or first notch forward from the safety notch of the friction lever 34 as shown in Fig. 3. This will place the lug 21 of the selector under shoulder 25 of the sear 23. Therefore when the selector is raised by the trigger, the sear 23 will also be raised as in Fig. 3 and the ig'ight hand barrel will be discharged. rlhe lug 22 which actuates lug 25 upon the left hand sear 24 has not moved far enough forward to rest under the shoulder 25 and therefore misses it as the selector is raised to fire the right hand barrel and leaves the sear 24 of the left hand barrel undisturbed. Vhen the trigger' is raised as is previously described, it also raises and releases the forward end of the sear actuating slide 12 from the groove 44 and allows the slide to move forward against the shoulder of the trigger. Therefore, when the trigger is released, the nose 13 of the automatic slide 12 strikes the top surface of the tang 2 and slips along over the shoulder 45 of the trigger as the trigger moves on down until the top is level with that of tang 2. The automatic slide being acted upon by the lever 40 and under the iniiuence of spring 41, moves forward until the transverse lugs 15 lie beneath both sears, as in Fig. 4. Therefore, when the trigger is again pulled, the automatic slide will be again raised and with it both sears. Hence the remaining coclred hammer will be released, thereby firing the left hand barrel. The recoil trigger locking mechanism will fulfil its functions as previously described. After either Vone or both barrels have been fired, the mechanism may be brought baclr to safety by sliding the safety slide 31 back to its safety position, or if the gun is reloaded or broken, in which instance the top snap D is turned, the mechanism will be automatically placed in its safety position due to the action of the breech lock 53 upon lever 46 of the automatic safety return mechanism previously described. To iire the left hand barrel first, the slide 31 is moved toits extreme limit of'forward movey ment in which position the selector Vstop dogs 27 will rest in the last notch 35 ofthe friction lever Srl. In thisposition the lug 22 comes in contact with shoulder 25 of the sear 24, whereby when the trigger is pulled it raises the same, releasing the hammer and firing the left hand barrel. ln this instance, the lug 2l which actuatesthe right hand sear will have moved forwardly and beyond the shoulder or lug 25 of the right hand sear, thereby leaving the rightv hand sear undisturbed. The automatic slide when the left hand barrel is iired acts identically the same as previously described for firing the right hand barrel, as does also the recoil trigger locking mechanism.

It is particularly pointed out that no flat springs are used in the mechanism. Coil springs are used instead and only two coil springs are necessary, namely, the spring 37 and the spring 41.

lt is particularly pointed out that the recoil trigger looking mechanism is a very important and integral part of the single trigger mechanism as no single trigger mechanism can be made practical orihave any value in which the involuntary pull before referred to is not compensated for. T he overcoming of this involuntary pull is a vital part of .the problem of forming a single trigger mechanism for double barreled guns.
